Abstract

The present disclosure includes a wheel assembly having a tie bolt retention system. Tie bolt retention systems of the present disclosure include retention holes and retention elements. Retention elements may engage retention holes to prevent loosening or disengagement of a tie nut from the tie bolt.

First claim

What is claimed is:

1 . A wheel assembly, comprising:
a first wheel section having a first outer surface, a first mate face, and a first bolt hole; a second wheel section having a second outer surface, a second mate face, and a second bolt hole, wherein the second mate face is configured to contact and engage with the first mate face, and wherein the second bolt hole is configured to align with the first bolt hole; a tie bolt having a threaded end and a length sufficient to pass through the first bolt hole and the second bolt hole, wherein the threaded end of the tie bolt comprises a first retention hole and a second retention hole spaced apart from each other; a nut configured to engage with the threaded end of the tie bolt; and a nut retention element engaged with one of the first retention hole and the second retention hole.

2 . The wheel assembly of claim 1 , wherein the tie bolt passes through the first bolt hole from the first outer surface and through to the second outer surface.

3 . The wheel assembly of claim 2 , further comprising a first washer positioned between a head of the tie bolt and the first outer surface.

4 . The wheel assembly of claim 2 , further comprising a second washer positioned between the second outer surface and the nut.

5 . The wheel assembly of claim 1 , wherein the first wheel section comprises a plurality of first bolt holes, wherein the first bolt hole is a member of the plurality of first bolt holes, the second wheel section comprises a plurality of second bolt holes, wherein the second bolt hole is a member of the plurality of second bolt holes, and the wheel assembly comprises a plurality of tie bolts, wherein the tie bolt is a member of the plurality of tie bolts.

6 . The wheel assembly of claim 5 , wherein each of the plurality of tie bolts comprises a threaded end and a first retention hole and a second retention hole positioned at the threaded end.

7 . The wheel assembly of claim 1 , wherein the first retention hole and second retention hole are located along an axis of the tie bolt.

8 . The wheel assembly of claim 1 , wherein the first retention hole and second retention hole are clocked with relation to an axis of the tie bolt.

9 . The wheel assembly of claim 1 , wherein a separate retention element engages with one of the first retention hole and the second retention hole of each of the tie bolts.

10 . A tie bolt assembly, comprising:
a tie bolt having a threaded end and a length sufficient to pass through a first bolt hole and a second bolt hole, wherein the threaded end of the tie bolt comprises a first retention hole and a second retention hole spaced apart from each other; a nut configured to engage with the threaded end of the tie bolt; and a nut retention element engaged with one of the first retention hole and the second retention hole.

11 . The tie bolt assembly of claim 10 , further comprising a first washer positioned between a head of the tie bolt and the first bolt hole, and a second washer positioned between the second bolt hole and the nut.

12 . The tie bolt assembly of claim 10 , wherein the first retention hole and the second retention hole are located along an axis of the tie bolt.

14 . The tie bolt assembly of claim 10 , wherein the first retention hole and the second retention hole are clocked with relation to an axis of the tie bolt.

15 . The tie bolt assembly of claim 10 , wherein the tie bolt comprises a third retention hole.
